instrumenting-first-party-metrics
instrumenting-first-party-metrics is a Product analytics & metrics skill for AI agents, published by PostHog in the posthog repository on GitHub. Skillspace rates instrumenting-first-party-metrics D (64/100) and it passed the safety scan; a judge model has also reviewed it.
How to instrument PostHog's own Metrics product from PostHog-owned code — record counters, gauges, and histograms that land in posthog.metrics, the same way customers do. Use when adding application metrics in this monorepo (web, Celery, Temporal), when asked to push or ship metrics into posthog metrics, or when unsure whether the SDK in this environment supports posthog.metrics yet. Covers the environment decision (SDK-first per the public docs, OTel fallback when the SDK path is not available), the exact version gates per SDK, what is already wired internally, and how to validate metrics actually arrive.

Outstanding specificity and a documented, hard-won gotcha (Temporal workers silently dropping OTel metrics) that most instrumentation guides would miss.
